The object of my invention is to construct a shoe blacking and polishingmachine which shall be set in Jmotion by the application anddownwardpressure of the foot of the person wearlng the shoe, and onewhich will complete the cleaning and polishing operation in a shortspace of time.

Inv general the device consists of a suitable base over which is mounteda cam plate carrying suitable tracks conforming to the gen` eral contourof a shoe, the said tracks being i adapted' to properly direct thebrushes vin their sweep about the shoe, and furthermore to glve, throughthe instrumentality of certain intermediate mechanism, the properinclination to the brushes as they contact wit-h the shoe in theirrotation about their own axes, thus causing the said brushes to makeContact with the entire surface intended to be polished. It consists tooof mechanism which will impart a slow motion to the brushes in theirrevolution or sweep about the shoe, and acomparatively rapid motionabout'their own axes.

The machine is composed of duplicate parts c so that both shoes Ican beoperated upon siin suitable bearings 2 the driving pulleys 3 connectedto any suitable source of` power. The driving shaft 4 of each pulley issuitably feathered and carries a sliding clutch mechauism 5 which whenmoved in a proper direction imparts motion to the gear wheel 59 (seeFig. 3) mounted on shaft 4which is journaled in bearing 60, and alsotothe bevel gear wheel 7 mounted on the same 'shaft 4. The two clutchesare linked vtogether by a series of 1evers 8 and 9 pivoted respectivelyin bearings lOand 11 ou the bed plate 1. From the pivotal point of thelevers8 and 9 there extends upwardly a rod 12 the lupper end of whichcarries a foot rest 13,.tl1e upper portion of saidV rod being suitablyguided by'a collar 14 projecting from `suitable shaft bearings on topofthe cam plate and to be hereinafter described.

The pressure ofthe foot on the rest 13 will depress the rod 12 and asthe latter is depressed it will by virtue of the link connections justdescribed cause the clutches 5 to be shifted in proper direction forimparting motion to thetgears 59 and the bevel gear 7. A gear wheel 6also journaledin bearing 60 and meshing with gear 59, meshes with a gear15..l

secured vto the end of a shaft 16 mounted in suitable bearings 17 at thebottom of a flat cam plate 18 (to be presently described)- IOO will bepresently described. Thetubular eX- tension 22 extends above the uppersurface of the cam plate 18, and to its upper projecting end are securedpreferably three arms 24, collectively called'a carrier. This carrier isbest shown in Fig. 2. At the meeting ends of each arm is secured a fixedbearing 25 in whichis mounted one end of a feathered shaft 26, theopposite end of which co-operates with a bevel gear 27mounted on thesliding bearlng 28 at the opposite end of said arm 24. The bottom ofeach sliding bearing 28 is provided with an anti-friction roller 29which is adapted to move in the outer cam track 30 of the cam plate 18.The shape of the track 30 conforms to the general contour of the shoe,and as the arms 24 rotate, the sliding bearings 28 are carried aroundalong the track 30, moving of course at the same time to and from thexed bearings25, within ysuitable guides 31 formed on each arm 24.

I have spoken of the shaft 26; I will now describe the mechanism forimparting motion thereto, and the manner in which said shaft impartsmotion to the brushes about their axes as they are being carried aroundthe shoe. The hollow shaft 23 above'referred to and which embraces therod l2 carries at 'its lower end a bevel gear 32 (see Fig. 7) whichmeshes with the bevel gear 7. The motion imparted to the hollow shaft 23is rapid as compared with that imparted to the carrier revolved by theworm gear 21. To the upper endof the hollow shaft 23' is secured a bevelgear 33 with which meshes the beveled pinion 34 of each feathered shaft26 above referred to. The feathered shaft 26 operates the bevel gear 27keyed thereto as bestshown in Fig. 5, and the gear 27 meshes with thebevele d gear wheel 35 mounted at the outer upper portion of the slidingbearing 28. The shaft 36 of the gear wheel 35 carries a fork 37 withinwhich is mounted by means of a pin 38 a block 39 and to the block 39 arepivotally secured the embracing arms 40 by means of a pin 41. The arms40 form the lower portion of the cylindrical stem 42 of the disk 43 overwhich the brush 44 is mounted and to which it is secured, As the arms 40freely span the block 39 and the block itself is adapted to oscillate onthe pin 38, it is apparent that this arrangement forms a knuckle jointat this point and thus allows the brush to be tilted to any desiredinclination.

`Loosely embracing the cylindrical stem 42 is a collar 45 to which arepivotally secured the ends of the arms 46 between the outer ends ofwhich is loosely secured the lever'47 having a pivotal bearing 48 on theupper sur- 'face of the sliding bearing 28. The lower end of the tiltinglever 47 carries an anti-friction roller 49 adapted to run in the camtracks 50 and 51 in a manner to be now described.

It is apparent from the above that as the carrier composed of therevolving arms 24 is revolved as already described, each arm will carryaround in the path of the cam track 30, the sliding bearing 28, and asbest seen from Fig. 4, the said bearing will carry the brush 44 with it,and while the brush is thus being carriedaround, it will at the sametime be ro-` tated about its own axis by the bevel gear wheel 35 meshingwith the bevel gear wheel 27 operated by the shaft 26. It is apparenttoo that as the brushes are thus carried around the shoe, they shouldsuccessively receive different inclinations so as to come progressivelyin contact with the different portions of the surface of the shoe. InFig. 4, while the lower end of `the tiltingv lever 47 is describing thepath of the cam track 50 the brush secured to its opposite end willassume one inclination, and when the lower portion of the same leverdescribes the path indicated by the outercam track 51, thejbrush willasgressively in contact with different portions of the surface of theshoe treated (see dotted positions of the brushes in Fig. 3). It becomesnecessary therefore to devise mechanism for shifting the lower Aend ofthe lever 47 from one cam track to the other and back again tothe irstso as to give different inclinations to the brushes i-n their revolutionabout the shoe. This mechanism is vas follows: Immediately above theworm gear wheel 21 (see Fig. 7) is secured to the tubular extension 22,a gear wheel 52 meshing with the large gears 53 on either side thereof,the said gears 53 depending from'the bottom vof the cam plate 18. Onopposite faces of the gear 53 and v diametrically separated from eachother, are secured segmentally curved guide strips 54. As the gear 53 isrevolved (it being revolved by the sh aft 16 which drives the carrierabove the cam plate) the guide strips 54 come successively in contactwith the arms 55 and .5 6 of a switch 57 pivoted in abearing 58 on thecam plate and in such a position that the switch oecomesa part of one orthe other cam track according tothe position occupied by said switch,very'much as aswitch on a railroad track. As the gear 53 revolves thestrips 54 of course operate the switch 57 alternately in oppositedirections, one strip 54 operating one arm 55 on one side, and the strip54 on the opposite side restoring the switch by operating the arm 56 onthe opposite side. Of course the switching voperation is not donesuddenly, it not being completed until the strip 54 has completelypassed the end of the arm 55 or 56, but the mechanism is so timed thatafter the'roller 49 has made a sweep of one track 50, it will be shiftedon to' the track 51, from which it willbe shifted back again on to thetrack 50, and so on iudefinitely; so that this arrangernent'will givethe brushes a varying inclination in their ro,-

tation, and during their revolution about the y doing this, which is tobe made thev subject matter of a separate application.

The operation is obvious from the description. It is apparent from thearrangement of gearing best shown in Figs. 1 and 7, that the motion forcarrying the brushes about the cam track andA thus about the shoe, is aslow one, this being necessarily so to give ample time for a polish; butthe motion for rotating the brushes about their own axes iscomparatively rapid so that a polished surface can be insured. The rapidmotion is imparted through the medium of gear '7, gear 32, hollow shaft23, gear 33, bevel pinion 34, shaft 26, gear 27, gear 35, shaft 36, andcylindrical stem 42 carrying the brush. It will therefore be seen thatas the brushes are carried around the cam tracks at a slow-rate, and

` in conformity to the contour of the shoe, they are rotated rapidlyabout their own axes, and progressively tilted or inclined so as tosweep the entire surface of the shoe to be cleaned and polished.
